Procurement Notes

Verify the specific ordering suffix 'K' against the manufacturer's official documentation to confirm pinout configuration and control features. Ensure compatibility with the required I2C bus voltage levels (1.71 V to 3.63 V) and check for moisture sensitivity handling requirements during assembly.

Selection Notes

Select this component when independent frequency synthesis with zero ppm precision is required across four channels. Verify that the target application supports the available output voltage levels (1.5 V to 3.3 V) and that the input reference signal falls within the supported ranges (up to 710 MHz for differential inputs).
